'Morning Edition' Returns: Panda Porn

It's never been easy to get pandas to mate in captivity, but zookeepers in China think they did the job with the assistance of some panda porn. They're working with a panda called Hua Mei, who was born in San Diego before being brought back to China. The 4-year old didn't seem to know what to do, so her keepers showed her an instructional video — which may have worked. Chinese officials say the panda is four months pregnant.
